object represents the reference to the data element referenced by an iterator. < / p >

classes have identical interfaces, and are treated the same by other STL classes. Since the < a class = "link" href = "ElementRef.html" title = "Chapter 24. ElementRef" > ElementRef< / a >
class inherits from the template data class, all methods have a _DB_STL_ prefix to avoid name clashes.< / p >

class corresponds to a single iterator instance. An Element object is generally owned by an iterator object. The ownership relationship is swapped in some specific situations, specifically for the dereference and array index operator. < / p >
